ThermalDry® Insulated Floor Decking™: Superior finished floor decking

It’s happened in thousands of basements: Homeowners pay good money to have attractive flooring installed, only to see this investment ruined by mold and moisture damage. The fact is that building materials (like framing lumber and plywood subflooring) that work well on the upper levels of your house can fail miserably in the basement. Plumbing leaks, spills, high humidity and dampness from your concrete slab can all result in moisture damage and a mold infestation.  

Wouldn’t it be great to install basement flooring that’s immune to mold and moisture damage? It would also be great if your floor could be comfortably warm instead of cold. ThermalDry® Insulated Floor Decking™ is designed to provide both of these important benefits.

Why choose ThermalDry® Insulated Floor Decking™?

Installing ThermalDry® insulated subflooring over concrete slab

Do it once, do it right. ThermalDry® Floor Decking is the best subfloor system available for use in basements and over other concrete slabs.

  • More comfort & energy efficiency. A continuous layer of rigid foam insulation will keep your floors warm and help cut your home heating bills.

  • Versatile. Use ThermalDry® Floor Decking in basements or anywhere you want to install flooring over a concrete slab.  
  • Quick to install. With ThermalDry® Decking, you install insulation & underlayment in a single step, with no fasteners required.
  • Greater headroom.  Save a full inch of basement ceiling height compared to a built-up wood floor.

The ultimate subfloor for any finished basement in Greater Philadelphia and Baltimore

Especially in a basement, the secret to a beautiful, long-lasting floor is the quality and durability of the subfloor that is installed. ThermalDry® Floor Decking achieves what other subfloor treatments can’t, providing a continuous layer of waterproof foam insulation that keeps your floor surface comfortable. Bonded to the rigid foam is a flat composite board that won’t attract mold and can’t be damaged by moisture. The composite board makes an excellent substrate for the finished basement flooring of your choice.
